WATER-DRIVEN SPINNING-CUP DEVICE FOR ARTIFICI SILK.

Application filed December 15, 1921. Serial No. 522,667.

To all whom it may concern:

Be it known that l, ALFRED LEHNER, a citizen of Switzerland, residing at Theresienthal, near Arnau, Czecho-Slovakia, have invented certain new and useful Improvements in WatenDriven Spinning-Cup Devices for Artificial Silk, of which the followingis a pecification.

This invention comprises improvements in and connected with spinning cup devices for the spinning of artificial silk, and. is concerned with that type of apparatus in which a plurality of turbines, each adapted to drive a spindle for supporting a spinning cup, are arranged in a common casing which receives the exhaust from the turbines.

The object of the present invention is to provide an improved construction in which each turbine, the spindle driven thereby, and the bearing for the latter, form a unit removable as such from the common casing, the said unit comprising means for eilectively closing in an acid tight manner the aperture through which the unit is inserted into the casing.

According to the present invention, the

spindles and combined turbines are each supported in a housing which depends within the casing, the said housing carrying the bearing for the lower end of the spindle, the upper end of which passes through a suitable packing gland in the housing. A faced flange is provided on the housing which is adapted to bear upon a corresponding seal upon the top wall of the casing, the parts being maintained acid tight by the mere weight of the housing and the parts carried thereby. In order to prevent interference of one with another of the series of turbines and also to strengthen the casing, there is preterably provided between adjacent turbines a transverse wall which terminates at a distance above the bottom of the casing and therefore does not obstruct the exhaust of the'various turbines through an outlet common to them all.

In order that the invention may be clearly understood, reference is made to the accompan ing drawings, which illustrate one embodiment of the invention.

Fig. 1 is a plan of five spinning cups mounted above five turbines to form one group.

Fig. 2 is a section on line AB oi Fig. 1, a compartmental device being also shown for containing the spinning cups.

Fig. 3 is a section on line (Li-D of Fig. 2.

Reference character 5 designates the spinning cups which are mounted on the upper ends of vertical spindles 6 extending from the respective water driving means beneath, and each comprising a turbine wheel a supported by a housing 0 provided with a bear- 1ng for the lower end of the spindle b. The said water driving means are actuated by water under pressure and are arranged in a casing 03 which encloses all the wheels or turbines for the spinning cups of one group. Each drive has its respective supply nozzle, these nozzles being designated f The spinning cups are arranged freely above the top of the casing 02. The water driving means, as can be seen from Figures 2 and 3, are quite separate from the spinning cups. Each housing 0 is formed with a faced flange c which is adapted to bear. upon a corresponding seal upon the upper wall of the casing 03 and close in an acid-tight manner the aperture in the casing through which the housing 0 is inserted, whereby disturbances or influences due to acid are absolutely eliminated. The casing has a single water outflow at 9 through which the exhaust of all the drives of one group ilows. Also the casing is provided with transverse walls or partitions it terminating at a distance from the bottom of the casing. 'lhese walls or partitions serve to prevent interference of one turbine with another and also serve to strengthen the casing structure.

Having particularly described one embodiment of the invention, 1 claim:

1. An apparatus of the class described, comprising a casing having an aperture in its top wall, a housing mounted in said aperture and having means for edecting a water tight closure thereof, a spindle supported by said housing and projecting from the top thereof, and a turbine wheel supported by said housing in said casing for operating said spindle, said housing and the parts carried thereby forming a unit which is adapted to be withdrawn from or inserted in said casing at will.

2. An apparatus of the class described, comprising a casing having a plurality of apertures in its top wall and a discharge outlet in its bottom Wall, housingsmounted in said apertures and having means for effecting a water tight closure thereof, a spindle and ,a turbine wheel connected thereto supported by each housing, said housings and the parts carried thereby each constituting a unit which is adapted to be inserted in or withdrawn from said casing at will.

3. An apparatus of the class described comprising a casing having an aperture in its top wall, a housing mounted in said aperture and having a flange resting on the top marginal portion of said aperture and effecting a water-tight closure of said aperture, a spindle supported by "said housing and projecting from the top thereof, and a turbine .wheel supported by said housing in said casing'for' operating said spindle, said housing spindle, and turbine wheel constituting a unit adapted to be withdrawn from or inserted in said casing through said aperture.

4. An apparatus of the class described, comprising a casing having a plurality of apertures in its top wall and a discharge outlet in its bottom wall, housings mounted in said apertures and having flanges resting on the top marginal oi'tions of said apertures to effect water-tlght closure thereof, a

menses 5. An apparatus of the class described,

comprising a casing having a plurality of apertures in its top wall and a discharge outlet in its bottom wall, housings mounted in said apertures and having means for effecting water-tight closure thereof, 'a spindle and a turbine wheel connected thereto supported by each housing, said housings and the parts carried thereby each constituting a unit which is adapted to be withdrawn from or inserted in said casing through said apertures, and partitions in said casing extending from the top wall thereof and terminating at a distance from the bottom wall dividing said easing into a plurality of compartments, one for each housing.

In testimon whereof I aflix my signature in presence 0 two witnesses.

ALFRED LEHNER.
